2 Claims.

This invention relates to improvements in paper-making apparatus and isdirected more particularly to improvements in paper-making apparatus ofthe Fourdrinier type.

The principal objects of the invention are directed to the provision ofa paper-making machine of the Fourdrinier type wherein the parts forforming a web such asthe shake rails, deckle straps, head box andrelated units are supported by a structure which is pivoted for up anddown movements. In this way the related parts are moved simultaneouslyand novel means affects the up and down movements thereof sothat theupper paper-forming run of the Fourdrinier wire may be disposed invarious angular positions or in various planes at an incline relative tothe horizontal as may be desired. The up and down movements of thesupporting rails is readily and easily affected so that the inclinationof the Fourdrim'er wire may readily assume different inclined positionsto accommodate different kinds of stock received thereby from the headbox and/or bring about various other desired results.

As a special feature of the invention, the principal parts of theweb-forming mechanism, such as the head box, Fourdrinier structure,etc., are supported by supporting rails and movable thereby in theirproper relation. This eliminates the necessity of adjustable connectionsbetween the Fourdrinier Wire, head box and other related units whichwould be required if the Fourdrinier wire were moved up and downrelative to the co-operating web-forming parts. As one novel feature ofthe invention means is provided to guide and steady the supporting railswhereby they may be secured in various positions of adjustment.

Various novel features and advantages of the invention will behereinafter more fully referred to in connection with the accompanyingdescription taken in connection with the accompanying drawings which,for purposes of disclosure, illustrate the present preferred form of theinvention. In the drawing:

Fig. 3 is an enlarged plan view of the adjusting mechanism of themachine taken at one side of the forward end thereof.

Fig. 4 is a fragmentary elevational view of one of the columns to showcertain details of construction, and

Fig. 5'is an elevational view of one of the guide and steady devices forthe supporting rails.

Referring now to the drawing more in detail the invention will be fullydescribed.

Supporting rails 2 are provided at the forward and rear sides of themachine which are spaced apart by cross rails or tiemembers 4. Themembers 4 are suitably secured to the rails to provide therewith astrong rigid supporting structure.

The supporting rails 2 may consist of I beams or any other suitablelongitudinally extending members but in the preferred form of theinvention however they are shown as comprising a pair of channel memberssuch as 3 disposed in back to back relation as in Fig. 2. These rails,as will appear, support the head box, shake rails, carrying rolls forthe Fourdrinier wire, suction boxes, etc. v

The stationary end of the machine is represented by S and may includefront and rear side frames of any suitable form such as it]. A couch ofusual form is represented by C. Pivot brackets I2 are suitably securedto and extend upwardly from the ends of the supporting rails 2 adjacentthe stationary end of the machine. Other brackets I l extend forwardlyfrom the frames I0 and are pivoted as at it to the brackets [2. In thisway, the rails 2 are hinged or pivoted to frames ID at the stationaryend of the machine so that they may be moved up and down to change theplane of the paper-making runof the Fourdrinier wire or to incline itmore or less with respect to the horizontal.

The head box of usual form is represented at H. It is from here that thepaper-making material is delivered onto the Fourdrinier wire. Spacedcolumns l8 are located at the front and back of the machine adjacent theforward ends of the rails 2. Each column may include a shaft 20 carryingon its upper end agear 22 which meshes with a worm or gear 24 carried bya horizontally disposed shaft 25. 1

- The shaft 26 is preferably rotatable by means of'a hand wheel 28 andextends from the column I8 at the front side of the machine to thecolumn at the rear side of the machine. In this way, the gears 22 ofboth columns may be operated simultaneously.

The front side of the columns l8 may be slotted as shown at IS in Fig. 4and block members 28 may be slidable up and down therein. The shafts 20are threaded as shown and are in threaded engagement with the block 28.In this way, as the horizontal shaft 26 is rotated in one direction orthe other, the blocks 28 may be raised or lowered.

Pins such as 30 carried by the blocks have links 32 thereon, the lowerends of which are pivoted at 34 to extensions such as 36 of thesupporting rails 2. The forward ends of both rails are, of course,similarly connected to the block 28 of the column adjacent thereto sothat both of therails are moved up or down simultaneously. Of course,means other than that described may be employed for raising and loweringthe rails, it only being sufficient for the purposes of this inventionthat both rails be acted upon simultaneously.

Shake rails of usual form 4!) have their rear ends pivoted by such meansas a stud or bolt 42 or the like to extensions 44 of the brackets 12 sothat the rails may be vibrated in a horizontal plane or in a planesubstantially parallel to that of the upper run of the Fourdrinier wire.The forward ends of the rails 40 have associated therewith a breast roll46 while their foremost end portions are associated with suitablesupports 48 as shown so that the forward ends may move slightly in ahorizontal plane.

Deckle frames 50 are carried by supports 52 and deckle pulleys 54 areassociated with the deckle frames 50. Other deckle pulleys 56 aresuitably associated with the stationary end S of the machine and supportdeckle straps 58 in such a way that one is located on the front and oneon the back side of the machine in proper relation with respect to thewire. The rails are vibrated by novel means more clearly shown in Fig.2.

Save-all pans and trays are represented by 3| and 35 supported as usualby standards 33.

The shake rails may be vibrated by means of the mechanism now to bedescribed. Links 66 and 62 are pivoted at their lower ends in brackets61 and 63 respectively while their upper ends are pivoted to a member 64which slidably embraces a vertically disposed rod member 66 carried by abracket 68 associated with one of the supports 48. A connecting rod 10is connected to the vibrating structure and may be operated back andforth by any well-known means so as to vibrate or swing the shake railsslightly in a horizontal plane while the structure permits the up anddown movement of the opposite ends of the rails without interferencewith the operation of the vibrating mechanism.

The Fourdrinier wire is represented by W. Its upper run is supported bythe usual rollers 12 and its lower run passes over and under carryingrolls 14. The wire W passes up and around the breast roll 46 in theusual manner into position to receive paper-making material.

It will be observed that the supporting rails are arranged and adaptedto form a rigid supporting structure and that the said structuresupports the shake rails, deckle frame, head box and other parts usuallyassociated therewith in such a way that the same may be moved up anddown and the making run of the Fourdrinier wire may be positioned atvarious inclined planes relative to the horizontal.

Thus, the inclination of the paper-making run of the wire may be changedat will and the Fourdrinier wire, head box and associated parts mayco-operate for the paper-forming operation at any position ofinclination without the necessity of making various adjustments betweenthe wire and the head box and associated parts. Both supporting railsare moved simultaneously by means of the mechanism associated with thecolumns. It will be appreciated that if desired the shaft 26 may bethreaded in the gear 22 or any other means may be adapted to facilitatethe raising and lowering of the ends of the frames.

It is desired to guide the rails 2 for up and down movements and tosteady them in various positions of adjustment. To that end steadyingmembers 35.! are provided which extend in a vertical direction and aredisposed adjacent the rails or may pass through the space between thechannels thereof when channels are used to form the supports. As shownin Fig. 5 tiglr'eners 8! in the form of screws are associated with therails and have their heads slidable in slots 85 of the members 80, asshown. Nuts 83 in threaded engagement with the screws bear on the railsand in this way, the members 81 may be loosened to facilitate movementsof the rails 2 and subsequently tightened so that the rails 2 areclamped to the members 80 and thereby held against slight movements orvibration as might be caused by the operation of the machine. This isimportant as it is necessary to hold the rails or steady them againstsuch movements as may be caused by the shaking of the rails. Anysuitable means may be employed for guiding the rails in their up anddown movements and to steady or clamp the rails in adjusted position.

It is desired to point out that by means of the invention theFourdrinier wire, the supporting means thereof, the head box and relatedparts are supported in such a manner that a complete machine is movableinto various adjusted positions. This is to be distinguished from merelychanging or adjusting the inclination of the Fourdrinier wire in whichcase various adjustments and connections must be made to provide theproper functioning of the related units.

By mounting the important related units on the supporting structure sothat their relation is unaffected by movements of the supportingstructure it is possible to readily and easily make such adjustments asmay be required. Even While the apparatus is in operation the wholestructure may be raised or lowered to cause the Fourdrinier wire to beinclined to suit different conditions or requirements.
